Application filed January 1 1904:. Serial No. 189,022.

To all 1072,0727, it may con/00772 Be it known that I, SIMON \V.lVAnmvnLL, a citizen of the United States, residing at Providence, inthe county of Providence and State of Rhode island, have invented newand useful Improvements in Cop-Tubes, of which the following is aspecification.

My invention relates to improvements in cop-tubes, or tubes forsupporting yarn packages, especially in cases where the yarn must besubsequently removed from the tube by unrolling.

My improved cop-tube is partilcularly intended for use in warp-creels.

Figure 1 is a perspective view of the coptube; Fig. 2, a sectional viewshowing, in addition to the structure, the manner in which the cop-tubeis secured to the winding-machine spindle.

My invention consists-in building the tube of alight shell (1 of paper,fiber, or other suit able material, with protecting end pieces 7) 7),each of which projects within the shell and is formed with an axial borea and a cupped or concave inner end (Z. The end pieces 71 may be of woodor any firm material and are directly and securely fastened to the shellby cementing or other suitable means. Both end pieces are formed withshoulders a, which abut and protect the ends of the fiber shell, and amutual protection is afforded the end pieces by providing for the shellto project slightly beyond their peripheries. One of the end pieces ispreferably formed with a transverse recess f across the axial bore 0, orboth pieces may be so formed.

W hen a yarn package is wound, the tube secured to the winding-spindlein the manner indicated in Fig. 2. The dog or driver 9 {a part of thewinding-spindle h) engages the recess f. This engagement is maintainedby the spring-catch '27, which prevents longitudinal displacement of thecop-tube on the spindle. The cupped or concave inner ends (Z of the endpieces 7) Z) are to facilitate mounting the cop-tube on both thewinding-spindle and the creel-spindle. Acting a funnel, they guide theend of the spindle to the axial bore 0.

Other forms of built-up tubes and spools have been attempted, but noneso simple and 5 efiective as that herein described. The manner'o't'securing the ends has been less protect ive, and therefore the cop-tubehas been more liable to damage and destruction.

in my improved cop-tube the ends of the 5 shell in are protected by theend pieces 7/ 7), preventing the disintegration of the luminarystructure of this part of the tube, and, further, the shell in turnprotects the end pieces from damage or destruction. llhrough itsprojection beyond the periphery of the end pieces the shell provides asorto'f surrounding cushion or buli'er, so that when the tubes a :ethrown about, as is the practice among operatives who use them, the endsare saved from being dent- 5' ed or broken.

For warping purposes it is desirable that the cop-tube be of relativelylarge diameter in order to maintain the tension of delivery as even aspossible. Therefore a cop-tube of such composite structure as describedis of great advantage. Large numhess of these tubes are handled daily inthe mills, and it is obvious that when light they can be handled muchmore easily and expeditiously than if solid and massive. Further, theheavier solid spools and tubes are more susceptible to damage, for whenthrown about in handling they become chipped and scarred and in useinjure the yarn. initially expensive their rapid dcterioration resultsin great cost of n1aintenance.

As above indicated, my improved cop-tube is ii t, and therefore lessliable to damage, and, i irther, is particularly designed to meet thedestructive conditions to which such cope subjected. um as my invention'2. in a liangeless cop-tube, the combination with two end pieces 7) 7;having shoulders. 13 w, axial bores 00, cupped inner ends (Jul and onethe end pieces formed with transverse LFL recessf, of a fiber shell aarranged with its ends abutting the shoulders c a and its peripheryprojecting slightly above the periphcries of the end pieces to protectthe latter from damage.
